Natalie continues to examine some advanced supplemental reading addressing monopolies and oligopolies and their impact on competition. As we are having a test on Thursday , we also reviewed budget terms such as balanced, surplus, and deficit, and reviewed the elements of a loan : principal, interest, and APR. We further discussed the role of a credit score. Tomorrow, we will continue reviewing the other material that will be on the test. For homework, Natalie is completing her lengthy essay on fiscal policy due on Thursday, and for tomorrow completing the study guide questions on the supplemental material on monopoly and oligopoly.
